Adsorption of gases on solid surfaces is exothermic reaction because – InterviewSolution

1.	Adsorption of gases on solid surfaces is exothermic reaction because
Answer» FREE energy increases ENTHALPY is positive Entropy increases Enthalpy is negative Solution :Adsoption is ACCOMPANIED by EVOLUTION of heat as the residual forces acting along the surface of adsorbent decrease i.e., ADSORPTION is accopanied by decrease in enthalpy.
